Brakes
Check Front Brake Fluid Level
1. Position the motorcycle on level ground with the front wheel
straight forward. Do not use the side stand. Position the
handlebars so that the brake fluid reservoir is level.
2. View the brake fluid through the sight glass (1). The fluid
should be clear and at a level in or above the sight glass. Add
brake fluid if necessary.
